Specification of Letters Patent.

Patented Oct. 5, 1915.

Application filed September 13, 1913, Serial No. 789,685. Renewed March 1, 1915. Serial No. 11,326.

b all whom it may concern:

Be it known that I, JOHN B. LEWIS, a citizen of the United States, residing at Kit Carson, in the county of Cheyenne and State of Colorado, have invented certain new and useful Improvements in Change- Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to change making machines and has for an object to provide a device of the class embodying new and improved mechanism for discharging coins totaling in value to the difference between the coins deposited and the amount of the sale.

A further object of the'invention is to provide a plurality of coin tubes for holding coins of various denominations under one dollar with slides beneath each of said tubes adapted to discharge a single coin from said tube and means for actuating one or more of said slides by mechanism controlled from a key depressed by the operator which depression actuates said slides to discharge coins of the value of the money deposited less the amount of the sale.

A further object of the invention is to provide in combination with cointubes and slides as above mentioned sliding bars adapted when raised to engage and actuate the slides with improved means forraising the bars into engaging position, the bars raised depending upon the depression of a lever corresponding to the amount of money deposited.

A further object of the invention is to provide a plurality of key levers designated to correspond to the amount of sale with other levers actuated thereby for moving the longitudinally movablebars to actuate the coin slides, such movement being accomplished by a movement of a sales key lever.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings: Figure 1 is a top plan view of the machine. Fig.2 is a longitudinal sectional view taken on line 2-'2 of Fig. 1. Fig. 3 is a top plan view of the machine with the sales key levers cutaway and shown in section. Fig. 4 is a top plan view with the sales mechanism removed and showing only the deposit mechanism. Fig. 5 is a transverse sectional view taken on line 55 of Figs. 1, 2, 3 and 4. Fig. 6 is a detail sectional view of one of the coin tubes. Fig. 7 is a detail view of one unit of the mechanism shown in normal inoperative position. Fig. 8 is a view of one unit showing the deposit key depressed. Fig. 9 is a view of one unit with both the deposit and sales keys depressed. Fig. 10 is a view of v one of the supporting rails showing the normal inoperative position ofthe coin slide operating bars. Fig. 11 is a view of one of the supporting rails with some of the operating bars raised into engaging position.

Like characters of reference designate corresponding parts throughout the several views.

The improved change making machine which forms the subject matter of this application comprises a frame 15 supported in any approved manner as upon the legs 16. The construction of the frame is wholly immaterial so long as it is arranged to accommodate the mechanism mounted therein and hereinafter described. At one end of the frame a plurality of tubes C are erected of proper diameter to receive and accommodate a column of superposed coins therein. As shown at Figs. 1 and 3 and reading from left to right the coin tubes will accommodate two stacks' of nickels, one stack of dimes, one stack of nickels, one stack of 25 cent pieces and one stack of 50 cent pieces. All of these coin tubes are similar except in diameter and the construction of the same is shown at Fig. 6. Immediately beneath the tube 0 a slide II is provided hav ing an opening 17 corresponding in diameter' to the tube and registering therewith in normal position, such normal position being secured by a spring 18 which holds such slide normally in position shown at Fig. 6. Beneath the slide H a plate 19is provided which prevents the passage of more than one coin into the opening 17 and also prevents the passage of such coin through the slide Huntil the plate is moved. The plate 19 is provided with an opening QOthrough of thesliding bar G. Theseveral sliding bars G are mounted to slide'in rails 23 and 24, the latter being provided with a keeper which prevents the bars G from vertical movement while the former is provided with slots as shown particularly at Figs. 10 and 11 which permit'the raising of the bars G. It will be noted especially from Figs. 2, 7, 8 and 9 that the hook 22 is capable of engaging with the cleat 21 only when the bars G are in raised position as shown in Figs. 8, 9 and 11. The raislng of the bars G and hooks 22 into such engaging position is part of the selective process carried outby the mechanism. To raise such bars G a plurality of rock shafts F are ournaled in the frame 15 extending transversely of the frame and having formed integral or rigid therewith cams f which engage under the barsG as shown at Figs. 7, 8 and 9 to at times raise such bars when the rock shafts are actuated. 'As shown at Fig. 4 the several rock shafts F do not all engage all of the bars G but only certain of said rock shafts engage certain of said bars@ The reason for such engagement will be hereinafter. more fully explained in explaining the operation of the machine- To actuate the rock shafts F deposit levers D are pivoted upon a bar 25 at the front of the machine and provided at their ends with keys properly designated in denominations of Scents from 10 cents to one dollar. The levers D are bell-crank levers and their lower legs are connected by means of rods B with the rock shafts F so that when one of the keys isdepressed one of the rock shafts F is rotated and raises suchbars G as are selectively actuated thereby. The raising of the bars .G throws their hooks into position to operate the coin slides and to provide for such operation sales levers S are pivoted at 26 and connected through the medium of rods A with rock shafts E which are also journaled upon the frame immediately above the rock shafts F. The bars G are provided with pins 27 extending laterally 7 from said bars and in position to be engaged by the dependingfingers e of the rock shafts E. It'willbe apparent, therefore, that as the rock shafts E are rocked their fingers e engage the pins 27 extending from said sliding bars G to slide said bars and actuate the coin slides.

the. deposit levers D is connected through the medium of a rodB with one of the rock shafts F. Proper springs 28 are pro vided to return the sales levers to'normal position while other springs 29' are provided to return the deposit levers D to normal position.

Taking theunit as shown at Figs. 7, 8 and 9 it will be apparent that by depressing the deposit key D the hooked end of the bar G will be raised into position to engage the cleat 21 and that'by depressing the sales key S the said bar will be'actuated to draw the coin slide H forward and drop a coin as de scribed in relation to Fig. 6, which said coin will slide down the inclined'chute 30 as shown at Fig. 2 into a position convenient to the operator. It will be obvious that not all of the units are actuated in the simple manner shown at Figs. 7, 8 and 9 but that certain selective combinations are necessary to produce a movement of the requisite parts to deposit the required change in the chute 30.

Assuming that the amount of money received is 50 cents and that the amount of the sale is cents the operator depresses the deposit key D and the sales key S 35. Through the depression of these two keys action of the. mechanism is set up as follows: The depression of key D 50 rotates rock shaft F 50 (see Fig. 4) whereby all of the bars G are raised except G 50 as will be apparent from an examination of said figure which shows a cam on rock shaft F 50 under each of said bars except under G 50. The bars G are, therefore, in position to engage coin slides aggregating 50 cents.- in value of the several denominations of 25 cents, 10 cents and 5 cents. The depression of the kev S 35 rotates rock shaft E 35 which is immediately above rock shaft F in Fig. l. From an'examination of said figure it will be seen that the fingers of the rock shaft E 35 engage bars G '50, G 5 and G 10. lVith cents and the sale is 40 cents-the depression of the deposit key 50 produces the result as above described but the depression of the sales key S 40 serves to move the sliding bars G 50, G .5 and G6. As above described the bar G50 is not raised so that it moves without actuating its slide. and the slides which are actuated areslides G 5 and G 5, as shown at Fig. 5. If the amount deposited is one dollar then the deposit key D100 is depressed and from an examination of Fig. 4: it will be seen that the rotation of rock shaft F 100 raises all ofthe sliding bars G. If the amount of sale is 5 cents the change to be returned is obviouslv 95 ,cents. The depression of {the sales kevf S 5 actuates the rock shaft E Siandfrom an examination of Fig. 4 it will be seen that all o-fthe bars G are actuated except the bar 5 so that 95 cents in change is deposited in the chute 30. If, on the other hand, the sale is 95 cents the amount ofchange to be returned is 5 cents and the sales key S' 95 is depressed which rotates therock shaft E 95 andfrom Fig. 4 it will be seen that E 95 actuates only the bar G 5 .to depositb' cents in change in the chute. If the amount received is I 75 cents the depression of deposit key D 7 5 rotates the rock shaft F 75 to raiseall of the bars G, except G 25 sothatthebarsare raised to en'ga'recoin slides of a value of 75 cents. If the sale is 60 cents then the sales key S 60 will be depressed thereby actuating the rock shaft E 60 to move the sliding bars G 5 and G 10 depositing 15 cents in change in the chute. I

It will be understood that. it is not necessary that the money actually received be depositedinthe coin tubesC at the time of receipt,'the only requisite being that coins be maintained in said tubes of sufiicient value to supply the desired change. Provision is made for returning the entire amount in change. As for-instance if change for one dollar is required-the deposit key I) 100 is depressed which actuates the rock shaft F 100 to raise all of the bars Gr and the: change key Sch is depressed actuating the rock shaft E011 and it will be seen from Fig. at that the actuation of such rock shaft Ech will move all of the bars G simultaneously to return the full one dollar in change of the several denominations. The same is true of returning the change for 50 cents, the 50 cent deposit key being depressed which actuates the rock shaft 1* 50 to raise all of the bars G except G 50. The actuation of the change lever Sch will likewise rotate the rock shaft Ech to move all of the bars Gr, but as the bar G 50 is not raised only such bars as engage coin chutes aggregating 50 cents will be operated. For 25 cents change the key D 25 is depressed actuating the rock shaft F 25 to raise the bars G 5, G 5, G 5 and G 10. The actuation of the change key Sch moves all of said bars G but only the four bars aggregating 25 cents are in engagement with the coin slides and only 25 cents in change is deposited in the chute.

In Fig. 1 a key Sns is shown which is in tended to be actuated when no sale is made. This key is provided for use in conjunction with a registering apparatus which is not shown in the present invention. When no registering apparatus is employed which is the condition of the mechanism disclosed in this application the key Sns will have no function.
